利用能量方程研究了纳米结构多铁性复合材料的电、磁和磁电性能，并考虑了表面、界面和尺寸效应。基于Eshelby等效夹杂概念和Mori-Tanaka方法，建立了考虑自发极化和自发磁化的耦合热力学演化方程，求解了基体和夹杂中的弹性场。复合材料的自发序参量、压电/压磁特性、磁电耦合效应等物理性质与复合材料的应力状态和微观结构密切相关。磁电耦合电压系数在临界尺寸附近不稳定，在临界尺寸以下消失。该模型适用于各种复合材料结构。
Electric, magnetic and magnetoelectric properties of the nano-structured multiferroic composites were studied by using an energy formulation with the consideration of the surface, interface, and size effect. Coupled thermodynamic evolution equations with respect to the spontaneous polarization and magnetization were established, in which the elastic fields in the matrix and inclusions were solved based on the Eshelby's equivalent inclusion concept and the Mori–Tanaka method. Physical properties of the composite, such as the spontaneous order parameters, piezoelectric/piezomagnetic properties, and the magnetoelectric coupling effect are highly dependent on the stress state and the microstructures of the nano-composites. Magnetoelectric coupling voltage coefficient was unstable in the vicinity of the critical size and disappeared below the critical size. The model is versatile enough for various composite structures.
